Summary

Ukrainian Infosystems

Ukraine · AI-generated

business ukraine ipv4

The AS handle UKRINFOSYSTEMS-AS is held by Ukrainian Infosystems.

What it's used for

  • The address space carries corporate infrastructure, evidenced by reverse DNS entries pointing to isys.net.ua such as undef.isys.net.ua and 195-137-232-128.isys.net.ua.
  • The network announces 2560 IPv4 addresses across 2 prefixes with 3 observed neighbours, indicating a small-scale business or internal corporate estate rather than a large access or transit provider.

Notable

  • Registrants for both announced prefixes match the AS holder, identified as LIMITED LIABILITY COMPANY "UKRAINIAN INFOSYSTEMS" with the netname UkrInfoSystems-NET.
  • The address inventory consists of two distinct IPv4 blocks: 89.22.40.0/21 and 195.137.232.0/23, with no IPv6 prefixes in the inventory.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,783 prefixes, as published 2026-10-17. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
